Nosetests & Combined Coverage

I have many projects that I开发者_如何学JAVA'm programatically running:

nosetest --with-coverage --cover-html-dir=happy-sauce/

The problem is that for each project, the coverage module overwrites the index.html file, instead of appending to it. Is there a way to generate a combined super-index.html file, that contains the results for all my projects?

Thanks.

You can't combine the HTML directories. You can combine the .coverage data files, but you'll have to use coverage directly, rather than through nose:

$ nosetest --with-coverage proj1
$ mv .coverage .coverage.1
$ nosetest --with-coverage proj2
$ mv .coverage .coverage.2
$ coverage combine
(combines .coverage.1 and .coverage.2 into a new .coverage)
$ coverage html --directory=happy-sauce

nosetests --with-coverage -i project1/*.py -i project2/*.py
